The Jinghong Hydropower Installed Capacity Of Comprehensive Analysis

The installed capacity of hydropower design option is an important part of it relates to the scale and efficiency of hydropower stations,investing and the investment return to the rational development of water resources use.Election too much capacity,the electricity market can not be consumption in a short period of time and investment recovery period of growth,investment rate of return reduced, capacity election too small,not sufficiency use of water resources,the economic benefits of hydropower stations can not be brought into full play.Therefore,the installed capacity of choice is a complex design of the kinetic energy of the economic problems.Currently at home and abroad have used conventional methods are:power. consumption balance,capacity utilization hours,such as flow,and other efforts, such as simplification of flow,flow frequency integral law.The existing method can be applied to small and medium-sized hydropower stations.For large basin installed capacity of hydropower stations choose,but also fully into account and research from the following aspects:1,upstream planning steps in the construction of hydropower station design;2, and the scope of the power supply market research;3,economically rational risk analysis and research;4,the shipping downstream impact analysis;5,the reservoirs on the impact of the Joint Dispatch and basin hydropower and the rational allocation of water resources;6,on the sustainable development of water resources.Based on Jinghong Power Station as an example,the large basin installed capacity of hydropower stations optimal choice for analysis and verification.Firstly, the scope of power and electricity market analysis,topographic and geologic conditions and the general layout pattern,rated head,kinetic analysis of the main economic factors on the Jinghong Hydropower Station to be installed for the early, and then with the development of the basin to be installed for early analyzed,the calculation and analysis of the hydro-energy targets,power consumption balance, the economic scheme of comparison,the impact on downstream shipping through analyzed,that the optimal capacity of the Jinghong Hydropower Station 1.75 million kilowatts(5×350,000 kilowatts).The scheme full utilization of water resource;coordination with upstream of the cascade hydropower stations better; meet the requirements of the general layout;in relative terms of economic;and meet the requirements of the downstream shipping.
